What is Syntheses and Crystal Structures of Copper Mixed-ligand Complexes of Multidentate Enaminones and Acetate Anions about?
Reactions of ferrocenoylacetone with 2-(aminomethyl)pyridine and N-(2-hydroxyethyl)-1,2-diaminoethane afford the multidentate enaminones HL 1 and H 3 L 2 , respectively. Reactions of copper acetate with the two enaminones generate the corresponding mixed-ligand complexes I and II, which are formulated as [CuL 1 (OAc)] and [Cu(H 2 L 2 )(OAc)], respectively. The structures of HL 1 , I and II have been determined by single-crystal X-ray crystallography. In complex I, HL 1 acts as a monoanionic tridentate donor via the carbonyl oxygen, deprotonated enamine nitrogen and pyridyl nitrogen atoms, the acetate anion is monodentate and the coordination geometry of the central metal is square planar. In complex II, H 3 L 2 is a monoanionic tetradentate ligand via the carbonyl oxygen, deprotonated enamine nitrogen, secondary amine nitrogen and hydroxy oxygen atoms, the acetate anion is monodentate and the coordination geometry of the central metal is a distorted trigonal bipyramid.
